Application filed July 12, 1917. Serial No. 180,045.

To all whom it may concern:

Be it known that I, FRANK P. HuMMnve, a citizen of the United States,reslding at New Haven, in the county of New Haven and State ofConnecticut, have invented a new and useful Improvement in Pocket-Knives; and I do hereby declare the following, when taken in connectionwith the accompanying drawings and the characters of reference markedthereon, to be a full, clear, and exact description 'of the same, andwhich said drawings constitute part of this application, and represent,in-- Figure 1 a-view in side elevation of one form which a knife havinga one-piece handle constructed in accordance with my in vention, mayassume.

Fig. 2 a view thereof in transverse section on the line 2-2 of Fig. 1.

Fig. 3 a plan View thereof.

Fig. i a view in detached elevation of a modified form of knife-blade,for 7 use in conjunction with my improved one-piece handle.

Fig. 5 a view of the knife in transverse section on the line 5-5 ofFig.1, showing, a. slight modification of my improvement.

Fi 6 a broken view in side elevationshowing the knife open.

My invention relates to an improvement low cost for manufacduce at anextremel convenient and safe ture, a simple, dura 1e,

pocket-knife, the handle of which is characterlzed by being made of asingle iece of ousmg for the sides and edge 0 the blade, and to providea spring therefor. y With these ends in v1ew, my 1nvent1on consists in apocket-knife having certam details of construction as will behereinafter described and pointed out in the claims.

In carrying out my invention as shown in Figs. 1, 2 and 3 inclusive, 1take a single iece of heavy wire and bend it midway of its less h into'two corresponding parts united y a trunnion loop 6 which passes througha perforation 7 in the shank 8 of a blade 9 which may be of any approvedltd tit)

form and construction, the said corresponding parts of the one-piecewire handle, each comprising a downwardly bent side-member 10, aloop-member 11, and a springmember 12. The side-members 1O aforesaid,are separated from each other so as to form object being to pro--between them a very narrow space or chambrought into contact throughouttheir length as shown in Fig. 2, and by preference are o ned together bysoldering 14: as shown in Fig. 2. The ends 15 of the spring-members 12coact with the lower edge 16 of the shank 8 so as to yieldingly hold theblade in its closed position as shown in Fig. 1 in which theyalso-co-act to protect its edge. When, however, the blade is thrown openposition as shown in Fig. 6, their ends 15 enter the notch 17 in theupper edge of the shank 8 and hold the blade in its open position, theshoulder 18 of the notch en gagingwith the rounded terminals 19 of theends 15 and reventing the blade from folding backwar so to speak. Itwill be noticed by reference to Fig. 3 that the pivot portion of the loo6 of the one-piece handle 15 made into its fully straight or the lengthof the perforation 7 in the blade shank 8., In the construction shown byFigs. 1 to 3 inclusive, the wire forming the onepiece handle must bepassed through thelpe oration '3 before the wire is bent intofiform toproduce the knifehandle. If desired, however, an inclined slot 20 may beformed in the shank F of the blade, a trunnion for the blade and aspring handle, after which the'slot is to blade '9 as shown in Fi a,permitting the Y bent to form a housing for the for cooperation with theshank of the blade to hold the same in its open and closed posi-- tions.

2. As a new article for manufacture, a pocket-knife comprising a blade,and a one- Mid piece wire handle having a trunnion-loop formed from thecentral portion of the wire, side-members for the protection of thesides of the blade, end-loops for the protection of f the point of thebla i which protect the edge of the blade and coe, and spring-membersact with the shank thereof for holding the blade in its open and closedpositions.

As a new article of manufacture, a

10 pocl ret-knife having a blade, and a onepiece wire handle bent toform a trunnion for the blade.

In testimony whereof, I have signed this specification in the presenceof two subscribing witnesses.
